Description

Technical Field

[0001] This utility model relates to the field of wiring components, and in particular to a shockproof wiring terminal. Background Technology

[0002] Terminal blocks are commonly used conductive connectors. One end is the wiring section for electrical connection to wires, and the other end is the connection section for electrical connection to connecting devices on electrical equipment. They are widely used in industrial production and daily life. In practice, the continuous and irregular vibrations of some electrical equipment can directly affect the stability of the connection between the terminal block and the equipment, leading to loosening. Although a matching positioning structure can be used to tighten the connection by surrounding the equipment and the terminal block, this method is complex, cumbersome to assemble, and costly. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a shockproof terminal block that can limit the lateral, vertical, and longitudinal displacement of the plug-in within the connection part when it is vibrated, thereby achieving the purpose of always pressing the plug-in tightly onto the connection part and preventing it from coming out of the connection part.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A shockproof terminal block includes a wiring portion and a connecting portion. The wiring portion is used to fix a wire, and the connecting portion is used to fix a connector for an electrical device. The connecting portion has a square shell structure with two open ends. One open end is connected to the wiring portion, and the other open end is adapted to the connector. Its sidewalls have a guide structure, a locking structure, a limiting structure, and a positioning structure, wherein:

[0006] The guide structure extends obliquely outward from the connecting portion and is used to guide the insertion of the plug into the connecting portion, including one or more guide plates;

[0007] The clamping structure is located in the middle of the connecting part and is used to press the plug-in against the inner wall of the connecting part. It includes a plurality of first cantilever springs and second cantilever springs: each first cantilever spring extends toward the wiring part along the insertion direction of the plug-in, and each is a bent structure that extends obliquely toward the inner side of the connecting part; each second cantilever spring is located beside a first cantilever spring and is an L-shaped structure, and its end extends to the side of the middle part of a first cantilever spring and extends obliquely toward the inner side of the connecting part.

[0008] The limiting structure is provided on the inner wall of the connection part near the wiring part and is used to limit the insertion depth of the plug in the connection part, including one or more baffles extending toward the inside of the connection part;

[0009] The positioning structure is located on the outer wall of the connecting part and is used to position the shockproof wiring terminal.

[0010] As a further explanation of the above technical solution:

[0011] In the above technical solution, the guide structure includes one or more first guide plates and two second guide plates: each first guide plate is disposed at the end of the connecting part away from the wiring part and extends obliquely outward; each second guide plate is disposed on a side wall of the end of each second cantilever spring near the end of the first cantilever spring and extends obliquely outward toward the end of the connecting part away from the wiring part.

[0012] In the above technical solution, two L-shaped clearance slots are arranged side by side on the side wall of the connecting part. The horizontal parts of the two clearance slots are both provided on the upper wall of the connecting part and are arranged in a straight line. Their vertical parts are respectively provided on the left and right walls of the connecting part. In each clearance slot, a first cantilever spring is formed on the side wall of its horizontal part away from the wiring part, and a second cantilever spring is formed on the side wall of its vertical part away from the first cantilever spring.

[0013] In the above technical solution, the positioning structure includes positioning grooves and cutting grooves arranged on the lower wall of the connecting part along the insertion direction of the plug-in, the cutting grooves penetrating the lower wall and forming the baffle on the side wall near the wiring part.

[0014] In the above technical solution, the wiring part is a U-shaped structure, its bottom wall is connected to the connecting part, and its inner wall has a number of slots arranged along its extension direction.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting multiple first cantilever springs and two L-shaped second cantilever springs, the lateral displacement, vertical displacement and depth displacement of the plug-in in the connection part can be limited when the plug-in vibrates, thereby achieving the purpose of always pressing the plug-in tightly on the connection part and preventing it from coming out of the connection part; by setting a guide structure and a limiting structure in the connection part, it is convenient to quickly insert the plug-in into place and operate conveniently.

[0025] like Figure 1-2 As shown, a shockproof terminal block includes a wiring portion 20 and a connecting portion 30. The wiring portion 20 is used to fix the wire 50, and the connecting portion 30 is used to fix the plug-in of the electrical device. The connecting portion 30 has a square shell structure and both of its opposite ends are open ends. One open end is connected to the wiring portion 20, and the other open end is adapted to the plug-in 40. A guide structure 01, a clamping structure 02, a limiting structure 03, and a positioning structure 04 are formed on its side wall.

[0026] like Figure 1As shown, the guide structure 01 extends obliquely outward from the connecting portion 20 and is used to guide the insertion of the plug-in 40 into the connecting portion 30. It includes one or more first guide plates 1 and two second guide plates 6. Each first guide plate 1 is located at the end of the connecting portion 30 away from the wiring portion 10 and extends obliquely outward. Each second guide plate 6 is located on a side wall of each second cantilever spring 3 near the end of the first cantilever spring 2 and extends obliquely outward from the end away from the wiring portion 20. In this embodiment, each side wall end of the connecting portion 30 is provided with a first guide plate 1 extending obliquely outward. Several first guide plates 1 form a structure similar to a square horn to quickly guide the insertion of the plug-in 40 into the connecting portion 30.

[0027] like Figure 2 As shown, the limiting structure 03 is provided on the inner wall of the connecting part 30 near the wiring part 20 and is used to limit the insertion depth of the plug 40 on the connecting part 30, including one or more baffles 4 extending toward the inner side of the connecting part 30; the positioning structure 04 is provided on the outer wall of the connecting part 30 and is used to position the shockproof wiring terminal, including positioning grooves 7 and cutting grooves 8 arranged on the lower wall of the connecting part 30 along the insertion direction of the plug 40, the cutting grooves 8 penetrate the lower wall and baffles 4 are formed on the side wall near the wiring part 20.

[0028] like Figure 3-6 As shown, the clamping structure 02 is located in the middle of the connecting part 30 and is used to press the plug 40 against the inner wall of the connecting part 30. It includes a plurality of first cantilever springs 2 and second cantilever springs 3: each first cantilever spring 2 extends toward the wiring part 20 along the insertion direction of the plug 40, and is a bent structure that extends obliquely toward the inner side of the connecting part 30; each second cantilever spring 3 is located beside a first cantilever spring 2 and is an L-shaped structure, with its end extending to the side of the middle of a first cantilever spring 2 and extending obliquely toward the inner side of the connecting part 30. In this embodiment, two L-shaped clearance grooves 5 are arranged side by side on the side wall of the connecting part 30. The horizontal portions 51 of the two clearance grooves 5 are both provided on the upper wall of the connecting part 30 and are arranged in a straight line. The vertical portions 52 are respectively provided on the left and right walls of the connecting part 30. In each clearance groove 5, a first cantilever spring 2 is formed on the side wall of its horizontal portion 51 away from the wiring part 20, and a second cantilever spring 3 is formed on the side wall of its vertical portion 52 away from the first cantilever spring 2. The structure of the bent cantilever spring is common knowledge to those skilled in the art. It includes a positioning end and a free end. The positioning end is fixed on the upper wall or side wall of the connecting part 30, and the free end extends into the clearance groove 5. During the insertion of the plug-in 40, the free end is pushed to deform. When the plug-in 40 stops moving, the reset rebound force of the free end can press the plug-in 40 against the inner wall of the connecting part 30 at the upper end and the left and right ends.

[0029] like Figure 1-4As shown, the wiring part 20 has a U-shaped structure, its bottom wall is connected to the connecting part 30, and several slots 9 are arranged on its inner wall along its extension direction.

[0030] like Figure 4-6 As shown, in use, the wire 50 is placed into the wiring part 20 and the two opposite side walls of the wiring part 20 are riveted to press the wire 50 tightly onto the inner wall of the wiring part 20 and into the slot 9 to fix the wire 50. Then, the wiring terminal is fixed in the appropriate position by the positioning structure 04. After completion, the plug 40 of the power device can be inserted into the connection part 30 to draw power. During insertion, several first guide plates 1 guide the plug-in 40 into the connecting part 30, pushing the two first cantilever springs 2 to deform outwards; the two second cantilever springs 3 guide the plug-in 40 forward within the connecting part 30, and the two second guide plates 6 on them guide the vertical displacement of the plug-in 40 within the clearance groove 5, and the two inclined horizontal arms on them press against the upper wall of the plug-in 40, pushing it against the bottom inner wall of the connecting part 30. Under the action of the recovery rebound force, the two first cantilever springs 2 press against the upper wall of the plug-in 40, further pressing it tightly against the inner wall of the connecting part 30. The baffle 4 restricts the forward displacement of the plug-in 40 on the connecting part 30, preventing the plug-in 40 from pushing the wire 50.

[0031] When the plug 40 vibrates, the vertical arms of the two second cantilever springs 3 can limit the lateral displacement of the plug 40 within the connecting part 30, and the lateral arms of the two second cantilever springs 3 and the two first cantilever springs 2 can limit the vertical and longitudinal displacement of the plug 40 within the connecting part 30, thereby achieving the purpose of always pressing the plug 40 tightly onto the connecting part 30 and preventing it from coming out of the connecting part.

[0032] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
